Methanizer - For low level CO and CO2 (by FID)

  • Converts CO and CO2 to Methane without changing retention times
  • Enables the FID Detector to detect low levels of CO and CO2
  • Removable Catalyst Jet for regular FID operation
  • Thermostatted to 380C
Methanizer - For low level CO and CO2 by FID)
The Methanizer option enables the Flame Ionization Detector to detect low levels of CO and CO2. It is installed as the removable jet in a special FID detector assembly. The Methanizer is packed with a nickel catalyst powder. During analysis, the Methanizer is heated to 380oC with the FID detector body. When the column efluent mixes with the FID hydrogen supply and passes through the Methanizer, CO and CO2 are converted to methane.
Since the conversion of CO and CO2 to methane occurs after the sample compounds have passed through the column, their retention times are unchanged. Hydrocarbons pass through the Methanizer unaffected.
Methanizer - For low level CO and CO2 by FID)
The special Methanizer FID detector assembly operates like the regular SRI FID detector, except that the FID temperature must be set to 380C. Due to the chemical relationship between nickel and sulfur, the Methanizer can ber poisoned by large quantities of sulfur gas.
